CROSS-REFERENCE TO RELATED APPLICATION(S)

This application is a continuation application of prior application Ser. No. 14/205,843, filed on Mar. 12, 2014, and claimed the benefit under 35 U.S.C §119(a) of a Korean patent application filed on Mar. 21, 2013 in the Korean Intellectual Property Office and assigned Serial No. 10-2013-0030290, the entire disclosure of each of which is hereby incorporated by reference.

TECHNICAL FIELD

The present disclosure relates to an apparatus and a method for recognizing a language input by a user. More particularly, the present disclosure relates to a linguistic model database for linguistic recognition, a linguistic recognition device, a linguistic recognition method and a linguistic recognition system in which individual linguistic model data from recognition-related information is taken into account in addition to general linguistic model data so as to improve precision of the linguistic recognition.

BACKGROUND

With the development of technological devices, input interface methods have been developed to accept input in various forms, such as a touch, a gesture, writing recognition, voice recognition, and so on. Most new input methods for terminals are based on recognition technology. In the case of the writing recognition, the voice recognition, or the like, recognition technology for recognizing a language is needed, and thus a recognition device may need a linguistic model-based process.

A structure of a linguistic recognition device varies depending on the relevant recognition technology.

FIG. 1 is a schematic view showing a linguistic recognition device according to the related art.

Referring to FIG. 1, the writing recognition language-based system 10 of the related art may operate as follows. First, handwriting pixel information from a writing input image, handwriting information based on a writing order, or the like, are obtained and then a character is recognized through a writing recognition engine 16 and a handwriting model database 12. Then, a word or a sentence is inferred by comparing the recognized character with a word or a sentence from a stored common linguistic model database 14. Next, a recognition result is determined from results recognized in a unit of a character or in a unit of a word or sentence.

In the word or sentence recognition, recognized characters linguistically constitute a word or a sentence, and results misrecognized in the unit of the character are corrected by comparison with similar words or sentences. The recognition engine needs a word database based on the linguistic model for a word recognition unit. In the case of a standalone recognition engine, a common linguistic model database 14 for storing general information for the recognition linguistic model is embedded in the recognition engine by taking general users into account. The common linguistic model data is optimized to accommodate many general users and thus updated over a significantly long period. Also, a training tool may be provided in accordance with the recognition engine. However, in this case a user has to train the engine, for example, by inputting a word to be trained, and other related processes.

Since the linguistic model database of the recognition engine is optimized to accommodate a general group of users, word recognition inference results may cause deterioration in recognition performance with regard to words (e.g., an abbreviation, etc.), to slang, to tone of voice, or the like, characteristically used by individuals, with regard to newly-coined words, informal terms, vulgar words, or the like, with regard to a person, a place name, or similar proper noun following a trend, or with regard to technical terms, informal terms, or the like, restrictively used in a group to which users belong (e.g., an age group, a school, a hobby society, or the like).

Therefore, a need exists for a device, a method and a system for providing a linguistic model database which improves the precision of linguistic model probability inference in linguistic recognition.

The above information is presented as background information only to assist with an understanding of the present disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the present disclosure.

In embodiments, the controller 130 may control the linguistic recognition engine 150 to recognize an input language, access the storage section 140 to store and delete data, and controls the communication section 110 to communicate with an external device 200.

The first controller controls the recognition-related information processor 160 to collect and analyze the recognition-related information used in the linguistic recognition device 100 and thus extract and store the individual linguistic model data.

The controller 130 may include Application Specific Integrated Circuits (ASICs), Digital Signal Processors (DSPs), Digital Signal Processing Devices (DSPDs), Programmable Logic Devices (PLDs), Field Programmable Gate Arrays (FPGAs), micro-controllers, or microprocessors.

The storage section 140 stores nonrestrictive data. The storage section 140 is accessed by the controller 130 and performs reading, recording, modifying, deleting, updating and so on with regard to data. The data stored in the storage section 140 may for example include various linguistic data received in the user language input section 110, in an operating system, in various applications executable on the operating system, in video data, in added data, or the like.

The linguistic recognition engine 150 may be achieved by software or hardware.

FIG. 6 is a flowchart showing a method of building a database for a linguistic recognition device according to an embodiment of the present disclosure.

Referring to FIG. 6, a method of building database for the linguistic recognition device according to this embodiment includes the steps of storing common linguistic model data in the storage section of the linguistic recognition device in order to stochastically infer a word or a sentence from a character acquired by recognizing a language input by a user at operation 5610; collecting the recognition-related information related to a user after storing the common linguistic model data at operation 5620; and analyzing the collected recognition-related information to be stored as the individual linguistic model data at operation 5630.

Referring again to FIG. 2, the storage section 140 may accumulate and store a variety of recognition-related information received in the linguistic recognition device 100. Of course, the recognition-related information may be stored in a compressed form.

The storage section 140 may include at least one storage medium type selected from among a flash memory type, a hard disk type, a multimedia card micro type, a card type memory (e.g., an SD or XD memory, etc.), a Random Access Memory (RAM), a Static Random Access Memory (SRAM), a Read Only Memory (ROM), an Electrically Erasable Programmable Read-Only Memory (EEPROM), Programmable Read-Only Memory (PROM), a magnetic memory, a magnetic disc, and an optical disc.

In the storage section 140, the common linguistic model data, i.e., linguistic model data basically provided by a device provider for typical linguistic recognition, is generally updated by a patch after a predetermined period of time elapses.

The common linguistic model data (DB) and the individual linguistic model data (DB) individually related to a specific user may be stored in different areas of the storage section 140 since they are different in an updating pattern.

The recognition-related information processor 160 collects and analyzes the linguistic recognition-related information used by a user in the linguistic recognition device 100 in order to acquire the individual linguistic model data, and stores it in the storage section 140 or updates it in real time. The recognition-related information processor 160 may be achieved by hardware involving software algorithm or software such as language searching and word extracting programs.

The collection and analysis of the recognition-related information may be achieved by collecting individual language in use and analyzing his/her own language type. There may be an abbreviated word (i.e., an abbreviation), an unusual ending type, or the like, that is different among users, and such a user's unique pattern is likely to get out of a range of the common linguistic model database. To this end, the linguistic recognition device 100 stores a user's input recognition result and analyzes its type to thereby determine a language type in main use.

In embodiments, the collection and analysis of the recognition-related information may include collecting individual mention information on the SNS or SMS, and analyzing a unique language type. That is, the recognition-related information processor 160 collects the mention information written by one user from the SNS and analyzes and determines a unique language type used on the SNS.

In embodiments, the collection and analysis of the recognition-related information may include collecting mention information according to user member groups on the SNS or SMS and analyzing a unique language type. That is, the recognition-related information processor 160 determines a user group related to a certain user by analyzing a relationship between users on the SNS or SMS, and determines a unique language type of a corresponding group by collecting and analyzing the mention information of users who belong to the determined user group.

In embodiments, the collection and analysis of the recognition-related information may include collecting and analyzing a new-coined word and a buzzword used frequently on the Web. That is, the recognition-related information processor 160 utilizes Web portal open API, or the like, on the Web to collect the new-coined word, the buzzword, or the like, which rapidly increases in a hitting rate, and thus determines a lifetime of the hitting rate through periodic monitoring.

In embodiments, the collection and analysis of the recognition-related information may include analyzing recognition information generated based on a user's account. If one user has many client devices, the recognition-related information generated in each client device may be stored and managed so as to share the recognition-related information among different client devices that s/he has.

FIG. 7 is a flowchart showing a linguistic recognition method according to an embodiment of the present disclosure.

Referring to FIG. 7, the linguistic recognition method of the linguistic recognition device 100 in this embodiment includes the steps of storing the common linguistic model data for stochastically inferring a word or a sentence from the character acquired by recognizing the language input by a user in the storage section of the linguistic recognition device at operation S710; by collecting the recognition-related information related to the user after storing the common linguistic model data at operation S720; by analyzing the recognition-related information to be stored as the individual linguistic model data at operation S730; by receiving the linguistic input by a user at operation S740; by recognizing the character from the input language at operation S750; and by recognizing a word by stochastically inferring a word or a sentence from the recognized character based on the stored common linguistic model data and individual linguistic model data at operation S760.

In FIG. 2, the linguistic recognition device 100 can autonomously build the individual linguistic model database (DB) to recognize an individual input language. However, if the linguistic recognition device 100 is a Smartphone, or a like mobile terminal, battery power consumed in autonomously building the individual linguistic model database (DB) and updating it in real time may be excessive. Also, if every client device a user has includes the recognition-related information processor 160, it may be uneconomical.

Referring to FIG. 8, the cloud based linguistic recognition method according to an embodiment includes the steps of storing the common linguistic model data in the storage section 240 of the linguistic recognition device 200 in order to stochastically infer a word or a sentence from the character acquired by recognizing the language input by a user at operation 5810; collecting a variety of recognition-related information related to a user in at least one client device 200, 400 including the linguistic recognition device 100 at operation 5820; transmitting the recognition-related information collected in the respective client devices for a predetermined period of time to the cloud server 300 at operation 5830; extracting the individual linguistic model data by analyzing the recognition-related information received in the recognition-related information processor 360 of the cloud server 300 at operation S840; storing the individual linguistic model data extracted by the recognition-related information processor 360 in the second storage section 340 at operation 5850; transmitting the stored individual linguistic model data to the linguistic recognition device 200 at operation 5860; storing (updating) the received individual linguistic model data in the first storage section 240 of the linguistic recognition device 200 at operation 5870; receiving a language input by a user at operation 5880; recognizing the character from the input language at operation 5890; and recognizing a word by stochastically inferring a word or a sentence based on the stored common linguistic model data and the stored individual linguistic model data with respect to the recognized character at operation 5900.

Below, operations of the cloud based linguistic recognition system according to an embodiment will be described.

In an embodiment, preconditions may be as follows.

-   -   1. On the premise that SNS user account information stored in         the linguistic recognition device (i.e., the client device) is         stored in consolidated user account on a cloud, a step of asking         for the consent of using user information may be performed.     -   2. With a consolidated user account, a real time popular search         word, or the like, may be acquired through a Web Portal open         API, Web Crawling, or the like (i.e., information collection         before doing the recognition).     -   3. With a SNS user account, user mention contents are taken from         an SNS site.     -   4. Natural Language Processing (NLP) is utilized to analyze and         determine a language pattern such as a word, a tone of voice, or         the like, and is mainly used by a user from the acquired user         mention contents     -   5. The open API, the Web Crawling, or the like, is used to         acquire a real time search word, a new-coined word, a buzzword,         or the like (hereinafter referred to as a ‘new-coined word’),         from the Web Portal.     -   6. The acquired new-coined word is monitored in a defined cycle,         and thus the lifetime thereof is determined to thereby determine         a point of time to add or delete the new-coined word.     -   7. The linguistic recognition device stores recognition results         such as writing, voice, or the like, in the consolidated user         account, and analyzes linguistic features of a user's input         information by analyzing the stored recognition results. Besides         the recognition results, linguistic features of the use of a         word, a change in endings, or the like, of the SMS are also         analyzed. The information about the individual linguistic         features collected and analyzed as above is stored in the         consolidated user account on a cloud, and a hitting rate, or the         like, is analyzed to determine a user's linguistic feature         information (i.e., building and synchronization of individual         linguistic model DB for cloud based recognition)     -   8. Information to be added to or deleted from a relevant user's         linguistic model DB are determined based on recognition-related         linguistic feature information collected from each client device         (i.e., the linguistic recognition device), the SNS, the Web, or         the like. All the linguistic feature information of the         individual linguistic model DB is determined whether to be added         or deleted by considering the hitting rate.     -   9. Version information, or the like, of the individual         linguistic model DB in the linguistic recognition device is         checked to update and synchronize the individual linguistic         model DB between the cloud server and the linguistic recognition         device.

In an embodiment, terminal recognition using the individual linguistic model DB may occur as follows.

-   -   10. The linguistic recognition device additionally performs a         general recognition step such as a letter recognition step, a         word recognition step utilizing the common linguistic model DB,         or the like and a word recognition step utilizing the individual         linguistic model DB.     -   11. The recognition results are transmitted to and stored in the         cloud server.

FIG. 4 is a schematic view showing a data management method related to cloud based linguistic recognition according to an embodiment of the present disclosure.

Referring to FIG. 4, the linguistic recognition device 200 includes a handwriting model DB 242 for character recognition of the handwriting recognition engine 250, a common linguistic model DB 244, and an individual linguistic model DB 246 according to the present disclosure.

The cloud server 300 may include an individual use word DB 341 where a user's input words in the respective client devices (i.e., the linguistic recognition devices) are collected and stored; a common new-coined word crawling DB 343 where new-coined words, or the like, on the Web are collected and stored; and an individual SNS use word DB 345 where a user's input words on the SNS are collected and stored. The individual use word DB 341, the common new-coined word crawling DB 343, and the individual SNS use word DB 345 are just described by way of example, but not limited thereto. Alternatively, another kind of DB may be added as necessary.

The recognition-related information processor 360 of the cloud server 300 analyzes the recognition-related information stored in the individual use word DB 341, in the common new-coined word crawling DB 343, and in the individual SNS use word DB 345, and thus extracts the individual use words or new-coined words excluding from the common linguistic model DB, thereby storing (i.e., updating) an individual linguistic model DB 346 with the extracted individual use words or new-coined words. The cloud server 300 uses the extracted individual use words or new-coined words stored (i.e., updated) in the individual linguistic model DB 346 to thereby periodically update the individual linguistic model DB 246 of the linguistic recognition device 200.

FIG. 5 is a schematic view showing a writing recognition system where cloud based user linguistic model data is managed according to an embodiment of the present disclosure.

Referring to FIG. 5, the linguistic recognition device 200 generates a handwriting input file (e.g., ink) based on handwriting input on a user input interface 210, and then performs linguistic recognition by carrying out feature extracting, character sorting, text splitting, word inferring and result decision through the writing recognition engine 250 according to the present disclosure. The foregoing handwriting recognition may use an alphabet DB 242 and a linguistic model DB 244 stored in the first storage section 240 of the linguistic recognition device 200.

The cloud server 300 may include a user use alphabet DB 342 received from one or more connected client devices, and an individual linguistic model DB 344. The individual linguistic model DB 344 of the cloud server 300 may be additionally updated with an individual use word directly input from the exterior, new-coined words on the Web, or the like. That is, the linguistic model DB 344 of the cloud server 300 includes the individual linguistic model data extracted by analyzing the recognition-related information received from the exterior through the recognition-related information processor 360 of the cloud server 300.

The alphabet DB 242 and the linguistic model DB 244 of the linguistic recognition device 200 may include the common linguistic model data and the individual linguistic model data. The alphabet DB 242 and the linguistic model DB 244 stored in the linguistic recognition device 200 may be periodically updated with the alphabet DB 342 and the linguistic model DB 344 stored in the cloud server 300 connected via a network.

Also, the linguistic recognition device 200 may include a voice recognition engine 270 embedded with a voice DB 247 for voice recognition. Likewise, the voice DB 247 embedded in the voice recognition engine 270 may be periodically updated with a voice DB 347 of the cloud server 300.

According to an embodiment, it is expected that in a recognition-related individual linguistic model database corresponding to individual or member groups, new-coined words on the Web are used to improve performance of recognition difficult to be processed by the common linguistic model database.

Also, it is expected that common recognition performance for a plurality of users is secured through a common linguistic model database, and additional recognition performance for a specific user is improved through individual recognition information management.

In embodiments, a hitting rate of a new-coined word, or the like, is traced and thus the new-coined word is added to or deleted from the individual linguistic model database in accordance with the hitting rates, thereby optimizing management of the individual linguistic model database.

In embodiments, the recognition-related information is managed based on a user account on a cloud server, thereby reflecting accumulated user-specified training results on to one or more client devices used by a user.
